A solid, a liquid or a gas.
Answer:
All of the above
Explanation:
Their all chemical change
Explanation:
21.0 g of potassium reacts with 62.5 g of barium nitride, what mass of potassium nitride will be produced
When wood burns, some of the mass is released as a gas. So if you were to combine the small fraction of ash with the gases released, you would get the mass of the original wood.
In a heterogeneous mixture, you can clearly see the distinction between the different substances within the mixture. e.g. fruit salad, paella, nachos
in a homogeneous mixture, it is still made up of different substances, but there is no way of distinguishing between them just from appearances. they have the same uniform composition throughout. e.g. salt water; you know it is made of salt and water, but the salt is dissolved uniformly throughout that you cannot tell.
hope that helps :)
